Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"The log collection feature is good and the solution is easily understandable. v""Loki also utilizes the same service discovery mechanism as used by Prometheus. So, whatever labeled metadata you see in Prometheus, you have the exact same metadata in the Loki system. Given this level of intricacy and the attempt to address these challenges, I firmly believe that Loki deserves praise for the work.""The effectiveness of filters is pivotal for optimizing the search process and extracting the specific information we need from the extensive log data.""The most valuable feature is the capability to set up alerts, which becomes necessary when we need to receive notifications for specific events.""The solution's stability has never been a problem. Stability-wise, I rate the solution a nine to ten out of ten.""The most valuable feature of Grafana Loki is the dashboards which are really simple to create.""We are using Grafana Loki as a database for real-time metrics.""I appreciate the capability to process logs from microservices and seamlessly integrate them into Grafana."

"This is a straightforward solution, easy to configure.""The ability to manipulate data in Splunk is unparalleled. Splunk’s powerful, flexible query language can morph difficult to understand log formats into usable data.""The varied prebuilt feature is the most valuable because it ensures that we have complete coverage over all of the key questions.""The solution has made us more secure.""The product is good, it satisfies our customers.""It's the completeness of the solution that we like the most.""It definitely does help with both auditing and as well as regular monitoring. SOC does more monitoring, but ES also gives you other features that are auditing-related. The dashboards are also beneficial.""It can log more logs than other solutions. It's a good way to troubleshoot problems."

Cons
"Visualization-wise, Grafana Loki's dashboard looks a little outdated compared to other open-source visualization tools like Chronograf.""The correlation of requests is not simple in Grafana Loki and can be improved.""We encountered certain limitations when it came to alerting, particularly when dealing with specific data sources.""There is a need for some change in the alerting types of the product. In short, a few changes in the alert area are needed due to minor shortcomings.""Enhancing speed could be a game-changer, and while it might vary depending on the application, it's a factor worth exploring.""The product must improve its UI.""The solution's scalability depends on the team managing the Grafana instance.""We had a well-structured dashboard with a functional query. However, an issue arose when the Kubernetes pod restarted. The statistics from our Grafana query would reset, dropping to zero and starting anew. This was particularly noticeable with linear graphs, which are expected to show consistent growth."

More Grafana Loki Cons →

"The configuration could be better.""Previously, they developed custom connectors or add-ons for a lot of applications. But that number can be upgraded still. There are a lot of applications in the world that are not supported.""We'd like to have the number of devices covered under the license to be increased.""The historical data extraction needs improvement. I would like the capability of taking data and having it trend longer.""There can be a bit of complexity around some fields during the initial setup.""It needs to improve the way to install third-party apps and enable installation without logging into splunk.com.""The threat detection system has room for improvement.""We were inundated with the amount of alerts and alarms that we could get out of it. It is also a resource hog and we didn't have the resources to support it on-prem so we're taking it offline now."

    Overview

    Grafana Loki is a powerful log aggregation and analysis tool designed for cloud-native environments. Its primary use case is to collect, store, and search logs efficiently, enabling organizations to gain valuable insights from their log data.

    The most valuable functionality of Loki is its ability to scale horizontally, making it suitable for high-volume log data. It achieves this by utilizing a unique indexing approach called "Promtail," which efficiently indexes logs and allows for fast searching and filtering. Loki also supports log streaming in real-time, ensuring that organizations can monitor and analyze logs as they are generated.

    By centralizing logs in a single location, Loki simplifies log management and troubleshooting processes. It provides a unified view of logs from various sources, making it easier to identify and resolve issues quickly. With its powerful query language, organizations can extract meaningful information from logs, enabling them to gain insights into system performance, identify anomalies, and detect potential security threats.

    Loki's integration with Grafana, a popular open-source visualization tool, allows users to create rich dashboards and visualizations based on log data. This combination enhances the observability of systems and applications, enabling organizations to make data-driven decisions and improve overall operational efficiency.
